Definitions

  • the invention relates to a method and system for presenting or reproducing information in a viewing especially of a driver of a vehicle, or a train, or a captain of a ship, or a pilot of an airplane or of any other person who has to gaze in a certain direction, especially for observing or monitoring the environment like for example a road in case of a vehicle driver.
  • SE 0201571-7 discloses a device for indicating an operational state of a vehicle comprising a display unit which shows graphical information in the form of an arc shaped scale extending from a first angle to a second angle and a number of numerals.
  • the operational state is indicated by a first segment which extends from the first angle to a third variable angle and which assumes a state that is visually distinguishable from the second segment between the third and the second angle.
  • each numeral is arranged to be able to assume a first normal format and a second larger format, wherein the latter is activated in the area around the relevant operational state.
  • This device is provided to reduce the time for transmitting the information concerned, like for example the speed of a vehicle, while retaining the precision, whereby the driver is able to keep his attention directed towards the current driving situation to a greater extent.
  • JP 07-280592A discloses a meter device for a vehicle, wherein a display mode of the meter device can be altered between a peripheral vision mode and a central vision mode in response to a judgment of a driver's sight line being separated from the meter device or not.
  • a general object of this invention is to provide a method and system by which the above mentioned risks can be further reduced and the safety especially of driving a vehicle can be further increased.
  • an object of the invention to provide a method and system for presenting or reproducing information in such a way that especially a person mentioned in the first paragraph who is operating a vehicle, airplane, ship or train, is less impaired with respect to his ability to detect changes in the environment, when reading such information.
  • a driver of a vehicle is enabled to read or recognize information by peripheral vision when his gaze is not directed at, or close to, an in-vehicle display or head-up display.
  • the information is presented by means of a display device in such a way that the driver's eye movements towards the information image (i. e. the presentation or reproduction of the information) and subsequent eye-fixations upon the information image are not necessary.
  • the information is readable or recognizable without having to move the eyes off the road.
  • the information is presented as simply and large enough to enable information extraction by peripheral vision.
  • the visual acuity of a human eye is greatest at the gaze point a person is looking at (which is defined as the visual 0° direction or gaze direction) and an area which extends to about 3° around the gaze point (angle of eccentricity).
  • This area of maximum of visual acuity is called foveal vision area or fovea.
  • the area surrounding this foveal vision area is called peripheral vision area in which the visual acuity decreases with increasing angle from the visual 0° or gaze direction (or eccentricity).
  • the area between 3° and 10° is also called the parafovea.
  • Figure 1 shows a diagram of this relative acuity V of vision (vertical axis) of a human eye in the nasal and temporal (i.e. to the temple) angular direction on the retina R in degree (horizontal axis) wherein 0° denotes the gaze direction.
  • the blind spot on the retina is indicated by a black area.
  • information is presented to a driver in such a way (especially with respect to its magnitude and/or thickness of letters or symbols and/or complexity and volume of content) that he can recognize it only by his foveal vision but not by his peripheral vision. This has the consequence that every time the driver wants to read such information he has to direct his view away from the road and onto the display on which the information is presented or reproduced.
  • the size of the information like especially text and line size of the presented or reproduced information, have to be enlarged and simplified to compensate for the loss of visual acuity in peripheral vision.
  • the amount of such enlargement and simplification increases according to Figure 1 in dependency on the angle of eccentricity in which the information is presented relative to the gaze direction.
  • the rules for the enlargement and simplification of information can be determined by trial and error or from the above established knowledge of contingencies.
  • a regression line can be used as an alternative to determine this enlargement.
  • Figure 2 shows such an equal magnification of letters on the basis of this equation (2) at ten times stimuli threshold size. If the viewer's gaze is directed on the central dot then the letters surrounding this dot are nearly equally "good” readable.
  • Figure 3 shows a side view into the cabin C of a vehicle with a driver D who is driving the vehicle and shows a preferred embodiment of a system for presenting or reproducing information according to the invention.
  • a main component of this system is a control device 10 for receiving information data to be displayed to the driver D and for processing these data so that at least one of the display devices 21, 22, 23 can be controlled for presenting or reproducing the information data to the driver D.
  • a first display device is for example a laser projector 21 which is provided and installed to project the information data for example onto a certain location of the windscreen of the vehicle or onto the dashboard.
  • a second display device is for example a usual screen 22 installed at a dashboard, and a third display device is for example a head-down display 23 (or a head-up display) for presenting the information data to the driver.
  • display device is used in this disclosure to refer to any source of visual information presentation to the driver.
  • displays include conventional computer displays, e.g. Liquid Crystal Displays (LCD) or similar, used to present GPS-based navigation and map information or other electronic devices, displays in the instrument panel, head-up displays, light emitting diodes (LEDs), and other projection displays.
  • LCD Liquid Crystal Displays
  • LEDs light emitting diodes
  • Helmet-mounted-, visor-mounted-, eyeglass-mounted displays can also be used.
  • a projection display is a commercially available diode laser (see e.g. www.lasershow.se) which is capable of producing color picture stimuli.
  • a picture stimulus is made up of a single laser beam which is moved around so quickly that the impression of an image is generated.
  • the beam is controlled by two small electromagnetic motors (x-, and y-axis) with a small mirror on the motor axis.
  • the use of a number of different lasers is advantageous, including a red and/or blue and/or green laser.
  • a simple, inexpensive laser such as those commonly used for as pointing devices for presentations in an auditorium; an automotive grade laser could be used as well.
  • the system comprises a push button or switch 30 on the instrument panel or steering wheel to be operated by the driver D for switching the system between a "Peripheral-Vision Information On"-state and a "Foveal-Vision Information On”-state.
  • the gaze position of the driver D is not detected and evaluated.
  • This system is designed in such a way that the driver D can decide by operating the push button or switch 30 whether the information is presented or reproduced by one of the display devices 21, 22, 23 in a way so that it is adapted to be recognized by peripheral vision or by foveal vision.
  • the control device 10 is provided to control the display device(s) 21, 22, 23 such that in the "Foveal-Vision Information On"-state the information is presented or reproduced for the foveal vision of the driver and in the "Peripheral-Vision Information On”-state the information is presented or reproduced for the peripheral vision of the driver.
  • the size of the peripheral information presentation or reproduction has to be enlarged and possibly simplified in comparison to the foveal vision presentation or reproduction as explained above.
  • the magnification and simplification for the peripheral information presentation/reproduction is predetermined and preset as fixed values either on the basis of eccentricity to the road center.
  • the above equations (1) or (2) can be used or they are evaluated by try and error.
  • the information is presented with a smaller size according to the enhanced visual acuity, e. g. by projecting the related image onto the windscreen in a location which is in the foveal vision area of the driver D.
  • the driver D can additionally select which kind of information he wants to be presented either in his foveal vision and/or in his peripheral vision.
  • peripheral presentation/reproduction of information can be provided either magnified (and possibly simplified) so that it is readable when directing the gaze onto the road, or in the usual manner i.e. without any magnification so that the driver can read it only when directing his gaze away from the road onto the related display.
  • Such selections can especially be made for reasons of a limited area to present information because the peripherally indicated information is presented in large size.
  • the selection can be made on the basis of the importance of the information. For example most relevant information like safety or collision warning is presented or reproduced in the foveal vision, less important information like navigation information is presented or reproduced peripherally and enlarged and simplified for recognizing in peripheral vision and all other information is presented or reproduced peripherally as well but in normal size for recognizing only when directing the gaze on it.
  • Another switch (not shown) can preferably be provided for selecting these types of information.
  • Examples of information-types that could be presented or reproduced are current speed, navigation information, text messages, or gear information. If the technological prerequisites (like especially transponders, camera based image processing for sign recognition, information rich digital maps which are based on GPS or other navigation systems) are provided, then traffic information can be presented to the driver in a readable peripheral vision format. Examples of such traffic information are current speed limit, traffic lights, the texts and images found on current road signs, information regarding upcoming hazards etc..
